DUMPING-WAGON.

Application filed July 6, 1914.. Serial No. 549,213.

and more particularly "to motor driven' dumping wagons and has for its objects the provision of simple and efficient mechanism for raising the body; means whereby the end gate will be gradually opened as the n body is elevated, and means whereby one or both ends of the body-may be elevated.

Other objects and the features of novelty will be apparent from the following description, taken in connection with the accompanying drawings, in which,

Figure 1 is a side elevation of a wagon embodying my invention the forward end of the body being shown in elevated position; Fig. 2 is a side elevation with both ends of the body elevated; Fig. 3 is a longitudinal section with the body in lowered position; Fig. 4: is a rear elevationof the end gate; Fig. 5 is a fragmentary longitudinal section through the end gate and delivery chute; Fig. 6 is a transverse section showing the hoisting mechanism; Fig. 7 is a detail section showing the pawl and ratchet mechanism for holding the hoisting mechanism; and, Fig. 8 is a fragmentary side elevation of the rear portion of the wagon with the end gate in the lowered position.

Referring to the drawings, 10 indicates the frame which is supported on the axles .11 and 12 in any preferred manner, the

axles being carried by the wheels 13. The vehicle is preferably provided with a motor for propelling it and the frame 10 carries a shaft 14 which may be driven by the motor through any suitable intermediate mechanism.

The frame 10 has pivotally mounted at opposite sides thereof the forward pair of hell crank levers 15, the upper arms of which are connected with the body 16 by means of links 17. The body 16 is provided with supporting members 18 which rest on the frame 10 when the body is in the lowered position. In the drawings the links 17 are shown as connected to the forward members 18. The frame 10 also has pivoted on opposite sides thereof the rearward pair of Specification of Letters Patent.

of upright posts 21 on which the tubularmembers 22 are adapted to slide. 1 The members 22 are pivoted to the body 16 at the point 23 and cooperate with the posts 21 to form. guides which steady the body during the operation of elevating it and also hold the body securely when in an elevated position. v

On opposite sides of the frame 10 are the depending *brackets 24 which support the cross shafts 25 and 26. The shaft v25 carries a gear or friction wheel 27 which is preferably adapted to be moved longitudinally of the shaft "into and out of engagement with a corresponding wheel 28 on the shaft 1 1. VVhen the wheels 27 and 28 are in engagement the shaft 25 will be driven by the shaft 14. The shaft 25'also carries the gears 29 which mesh with the gears 30 on the shaft 26 and thus form a driving connection between the two shafts. A ratchet wheel 31 is secured on the shaft 25 and engaged by a pawl 32 which is held against the wheel by means of a spring The pawl "82 is held by means of a fixed bracket 34 and a link 35, the latter connecting the upper end of the pawl with a fixed bracket 35. The lever 36 has operatively connected therewith an arm 36 by means of which the pawl may be disengaged from the ratchet wheel.

The lower armsof the levers 15 have attached thereto chains 37 which are wound on the shaft 26. From Fig. 3 it will be evident that when the shaft 26 is turned to wind the chains 37 thereon the levers 15 will be swung on their pivotal connections with the frame 10 so as to elevate the forward end of the body. The arms 19' of the levers 19 have connected therewith chains 38 which extend rearwardly around guide wheels 39 and then forwardly and connect with the chains 37 or the levers 15, as preferred, By this arrangement, when the shaft 26 winds the chains 37 thereon both ios the forward and rearward ends of the body the plates 42 and thus hold the wheels 39 in position. The blocks 40 are also additionally supported by means of links 44 which have their upperends pivotally connected with the frame 10.

When it is desired to elevate only the forward end of'the body engaged from the eyes .41, permitting the blocks 40 to swing. forwardly with the links 44 which support them.' (See Fig. 1.)

At the rearward end of the body .there is a gate 45 which is pivoted at the bottom-to slidable members 46 on the under side of the body. The members 46 are connected with arms 47 on a cross shaft 48 by means of links 49, the length of which may beadjusted. Byi rocking the shaft 48 the slides 46 will be moved 'rearwardly and swing the gate on its upper pivots 50, these pivots connecting the.

gate with quadrants 51, these quadrant-3y sliding in' suitable guides 52 on the body. The lower ends of the quadrants 51 are provided with openings by means of which they may be attached to pins 53 on the side of the body to'secure the top of the gate, as shown in Fig. 1. The lower ends of the quadrants Fig. 8.)

' is pivoted,

are also provided with lateral projections 54 which engage with the guides 52 when the gate 45 is swung downward on its pivotal connections with the members 46. (See For the purpose of automatically openin 48- carries an arm 55 and the outer end of this arm has pivoted thereto a link 56 which is adapted to be connected-with a fixed pin 57 on the side ofthe body, as shown .in Fig. 2, or with a pin 58 on the frame 10, as shown in Fig. 1. When the link 56 is arranged as shown in Fig.2, the body will be elevated without actuating the end gate, but when the link 56 is attached to the pin 58 the elevation of the body will cause the end gate to be gradually swung to the rear, as will be readily understood. I

he end gate carries a chute 59 on which. at the point 60, a gate 61 which, when in the position shown in Fig. 3, closes the opening 62 in the bottom of the chute and, when in the position shown in Fig. 5, formsa barrier across the chute and causes the material'to be discharged through the opening 62. The chute is also provided with depending 55 cars 63 to WhlCh an extension chute 64 may be attached for the purpose of delivering the material in diiferen-t directions.

It will be understood that the drawings are merely illustrative of one form of my inarm' 68, this arm being convention and that various changes in the form of certain details may be made without departing. from the spirit of the invention as defined in the claims and I therefore do not wish toibe limite tothe exact details shown and described; Y 5

aving' thus described the invention, what is claimed and desired to be secured by Letters Patent is: 1. In avehicle, a dump body,

the combination of a frame, oppositely arranged front and rear pairs'of bell crank levers pivoted to said frame and connected with said body, a single hoisting mechanism arranged on relatively the same side of both of said pairs of levers, flexible means extending directly from said mechanism to one of said pairs of levers, flexible means connecting said mechanism with the other of said pairs of levers, normally fixed guide members for said lastgate by means of links 69.

mentioned flexible means whereby the direc-' tion of pull'on said levers is reversed, and

means for detachably securing said guide members to render said other pair of levers 2. In a vehicle, the combination of a frame,

a dump body, oppositely arranged front and rear pairs of bell crank levers pivoted to said .frame and connected with said body, a single hoisting mechanism arranged on rela tively the same side of bothcpf said pairs of levers, flexible means extending directly from said mechanism to one of sa1d levers, flexible means connecting said mechanism'with the other of said pans of levers, 'normally fixed guide members for said lastmentioned flexible means whereby the direction of pull on said levers is reversed, means for detachablysecuring. said guide members to render said other pair of levers operative or inoperative, and means co5perating with said hoisting mechanism for holding the body in elevated positions, and comprising a post secured on said frame and a member slidable on'said post and flexibly connected with the body. 1

In testimony whereof I afiix my signature in presence of two witnesses.
